Brooklyn-based start-up Modern Meadow is currently developing the world’s first lab-grown leather. By taking advantage of recent advances in cell engineering, the company is hoping to shape a future that is “cultured not slaughtered.” The leather is grown by first isolating an animal's skin cells and then multiplying those cells by the billions, producing sheets of the faux-skins. Not only can this technology decrease leather-specific slaughterhouses, it will also open up opportunity for designs that wouldn’t be available naturally.
